Subject: Qterm/vt100 

I am using the cpm QTERM comm program with its vt100 emulator to talk to
our mainframe (UB-MTS) full-screen message system.
I am running QTERM on a Kaypro-II, a slow machine.
The problem I am having is that even at 1200 baud  sometimes the vt100 codes
coming in from MTS go by too fast for the Kaypro to keep up, and the screen
gets scrambled.  I checked this out at 300 baud, and at that speed it works
first time, every time, but that is impractical.
 
What I need is either a way to halt input from MTS while the Kaypro processes
the cursor and screen control codes, or a way to patch QTERM with what
I believe
is called an "interrupt driver".  I'm just parroting the term, I don't know
what it means.  
 
I have a fast terminal emulator (fastterm.com) that works at high speeds
without
dropping characters, apparently because it is interrupt driven.
 
Suggestions are solicited.  Please keep in mind that I relatively ignorant of
these matters, and have almost no experience in working with assembler.  If   
patching is an option you'll have to tell me how, as well as what to patch.
 
Thanks.
